Answer:
4x-12
Step-by-step explanation:
This problem is about triangles.
We must apply the trigonmetric relations to solve this.
I can see we have a right angle triangle.
Let's use the idea of the tangent.
tan (22º) = building height / shadow length
Let's plug given data on above formula:
tan(22º) = 610 ft / shadow length
I looked up and got tan(22º) = 0.40, so:
0.40 = 610 ft / shadow length
shadow length = 610 ft / 0.40
shadow length = 1,525 ft
Answer: shadow length is 1,525 ft .
Answer:
Triangle, pentagon, heptagon, and decagon.
Step-by-step explanation:
REMEMBER THIS:
DECAGON: 10 SIDES
HEPTAGON: 7 SIDES
PENTAGON: 5 SIDES
TRIANGLE: 3 SIDES
EXTRA INFO:
HEXAGON: 6 SIDES
QUADRILATERAL: 4 SIDES
OCTAGON: 8 SIDES
NONAGON: 9 SIDES
Answer:
Area for Triangle is: 1/2bh or bh/2
Area for Trapezoid (As shown in picture):
1/2h(b1+b2)
You’d have to do 1/2 x 18(15+37) for the quesyion in the picture
Hope this helped!
